Notes

The Troubleshoot option is available only if your copy of Windows 10 (Version 1607 or later) isn't activated.

Read the instructions on how to use the tool to create installation media for Windows 10 Home and how to do a clean installation.

During setup for Windows 10 Home, you'll be asked to enter a product key. Because you already have a digital license for Windows 10 Home, you can skip this step and continue with the installation. Windows will automatically activate using your digital license when the installation is completed.

A Windows 10 digital license is associated with your device. So if you make significant changes, such as replacing your motherboard, Windows will no longer find a license that matches your device. For help resolving this issue, see Reactivating Windows 10 after a hardware change.

If you need additional help reactivating Windows on your device, contact customer support.
